Component Testing

IMPORTANT: You must perform the Circuit/System Testing before proceeding with the Component Testing.
  1. Ignition OFF, remove the MAP sensor.
  2. Install a 3A fused jumper wire between the 5-volt reference circuit terminal 1 and the corresponding terminal of the MAP sensor.
  3. Install a jumper wire between the low reference circuit terminal 2 of the MAP sensor and ground.
  4. Install a jumper wire at terminal 3 of the MAP sensor.
  5. Connect a DMM between the jumper wire from terminal 3 of the MAP sensor and ground.
  6. Ignition ON, with the J 23738-A  or J 35555  slowly apply vacuum to the sensor while observing the voltage on the DMM. The voltage should vary between 0-5.2 volts, without any spikes or dropouts.
    • If the voltage reading is erratic, replace the MAP sensor.
